SPECIFICATION forming' part of Letters Patent No. 748,746, dated January 5, 1904.

Application tiled April 1D, 1903. Serial No. 151,997. (No model.)

To all whom, in' may concern,.-

Be it known that 1, WILLIS S. KELsEY, a citizen of the United States of America, residing at Meriden, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Parquetry for Floors, Paneling, &c., of which the l following is a specification.

The invention has to do with the finishing Io of wall, veiling, or floor surfaces by the application of blocks or panels, and more particularly it has to do with the means employed for securing these blocks or panels in place. Broadly speaking, it comprehends the use t5 of plates, preferably metallic, each plate engaging two or more blocks which are grooved about their edges for this purpose and means for securing the plates to the tioor or other foundation, the entire device when the surzo face is finished being concealed,

The invention is illustrated as applied to the laying of parquet-flooring.

Figure 1 is a general plan view showing the manner of use of the invention. Fig. 2 is a view similar to Fig. 1, butshowingfourblocks in position. Fig. 3 is a detail plan view of a single block, with parts broken away to show construction. Fig. 4 is an edge view of the same. Fig. 5 is a view of a bolster.

Referring to the drawings, the edges of the blocksa are grooved, as at b. Metallic plates c d, having arms m n, the arms 'm being slightly less in width than the depth of the groove and the arms n being in width about twice the depth of the grooves, are provided which engage these grooves, as shown, said 'plates being screwed to the Hoor. Recesses for the screws are made by cutting away the block below the groove, as indicated at e.

The plates e d are madein dierent shapes to meet the conditions of their use. The plate c, being used when four blocks are brought together in the field of the floor, has four arms and the plate d, being used to secure adjacent blocks along the edge of a room or against the base-board, having three arms, two of which, m, are slightly less in width than the depth of the groove, and the other one, fn, is wide enough to lie in the grooves in 5o the adjacent blocks when they are brought together. v

In laying a parquet-floor the first block laid is preferably in the corner of the room, as at 100. The plates d are then positioned, as shown in Fig. 1 at'lOl 102.- The next 55; blocks are then positioned so that the extendn ing arms on the plaies c d just enter the grooves in said blocks suiiciently to support the plate. The positions of the blocks at this time are shown at 110 112 115 in full 6o lines, Fig. 1. Iith the blocks in the posilionshere described the plates are fastened to the door, as by the screws g, which are driven sufficiently to cause the plate to bind the blocks to the floor. The blocks 110 112 65 115 are now driven together, sliding on theplates to their proper positions, as shown in Fig. 2. The recesses e, formed along the edges of the blocks, are necessary to permit Aof theblocks beingdriven to place without 7o interfering with the fastening-screws. Continuing in this manner the whole floor is laid, each plate binding two or more blocks being secured to the door by one, two, or three screws, as desired. It results from the use of such a fastening device that when the floor is completed the fastening-plates are entirely concealed. Every block is securely held to the door, and the finished surface of the blocks is in no way marred.

When thin blocks are used, it will be necessary to use quite thin fastening-plates, and

in any case when the plates are not stiff enough it may be advisable to provide a bolster, (showu in Fig. 5,) which is inserted under the plate and preferably surrounds the screw. Such a bolster will support the plate and keep it from buckling.

It is clear that the use of this invention is not limited alone to the laying of parquet- 9o flooring. It can as well be made use'of for securing paneling of any description whatever in place, and I do not wish to be limited to any extent beyond that made necessary by the state of the prior art.

I claim as my invention- 1. The combination with the blocks, said blocks having grooves in their edges thereby forming upper and lower ledges, the lower ledges at the corners being cut away, and the Ioo grooves at these points lying parallel therewith, of a fastening-plate having inclined sides received in the grooves and engaging corner of said plate, said projections having 1o the inclined port-ions thereof adjacent the their outer ends pointed.

corners of the blocks and being provided In testimony whereof I affix my signature with projections extending into the grooves in presence of two Witnesses.
